Open positions
Senior BackEnd (Physical design) Engineer
Leads full RTL-to-GDSII backend flow for semiconductor design, focusing on timing closure, low-power optimization, and physical implementation (floorplanning, CTS, IR-drop) while collaborating with design teams and external vendors.
Analog Design Engineer
Designs high-end ADC/DAC circuits for optical communication in advanced semiconductor processes, focusing on analog/mixed-signal IC development and verification.
Production Test Engineer – High-Speed Mixed-Signal ICs
The Production Test Engineer will manage and optimize test processes for high-speed mixed-signal ICs in a high-volume manufacturing environment. The role involves using ATE platforms to ensure device quality, troubleshooting test failures, and collaborating with design teams to improve yield.
Senior Analog Design Engineer
A senior analog/mixed-signal IC engineer who designs and technically leads high-end ADC/DAC and related analog blocks (PLLs, SerDes) for optical communication, from architecture and specification through verification and tape-out in advanced FinFET/GAA process nodes.
VLSI Design Engineer
VLSI Design Engineer/Micro-architect responsible for designing cutting-edge communication systems from scratch using ASIC/FPGA with Verilog/SystemVerilog.
BackEnd (Physical design) Engineer
The Backend Physical Design Engineer will manage the full RTL-to-GDSII implementation flow, including synthesis, floorplanning, and timing closure for high-frequency, low-power designs. The role involves collaborating with design teams and external vendors to ensure successful tape-out and silicon performance.
